Question

You have a photo that measures 1 in. wide by 3 in. tall. If you want to enlarge the photo so that the height is 18 in., what will the width of the photo be?

A. 98 in.
  B. 6 in.
  C. 108 in.
  D. 4 in.

Answer 1

Your answer would be B.) 6 inches.

Here's the math:

The height of the photo goes from 3 in. to 18 in. To get from 3 to 18 we multiply by 6. So, we must multiply the width by 6 to make sure that our photo is up to scale after the enlargement. Well 6*1= 6, which will be your final width.

So, your answer is 6 inches wide
